x:0,1-x:4-x * 3/4 =2,25
tim x
X :0,1- X :4 - X x 3/4 = 2,25
x=0,25
Tick cho mình nha Nguyễn Thùy Linh
X=0,25 nha ^^ (các bn nhớ k cho mik nha )
Tìm x:
x chia 0,1 - x chia 4 -x nhân 3/4 = 2,25
X : 0,1 - X : 4 - X x 3/4 = 2,25 giải chi tiết giúp mk nha
x x 10 - x x 1414- x x3434= 1,25
x x (10 - 1414- 3434) = 1,25
x x 9 = 1,25
x = 1,25 : 9
x = 536
Tìm X :
a) X : 0,25 - X = 15,6
b) X : 0,1 - X : 4 - X x 3/4 = 2,25
a)x÷0,25-x=15,6
X×4-x×1=15,6
X×(4-1)=15,6
X=15,6÷3
X=5,2
B)x÷0,1-x÷4-x×3/4=2,25
X×10-x×1/4-x×3/4=2,25
X×(10-1/4-3/4)=2,25
X=2,25÷9
X=1/4

X:0,1-X:4-Xx3/4=2,25
X : 0,1 - X : 4 - X x 3 / 4 = 2 , 25
X x 10 - X x 1 / 4 - X x 3 / 4 = 2 , 25
X ( 10 - 1 / 4 - 3 / 4 ) = 2 , 25
X x 9 = 2 , 25
X = 0 , 25
x * 4 + 1/2 * x =55,35
x : 0,1 - x :4- x *3/4=2,25
0,01m3 .....(< > =) 1/99
A : 0,1 - A : 4 - A x 3/4 = 2,25
A : 0,1 - A : 4 - A x 3/4 = 2.25
A x 10 - A x 0,25 - A x 3/4 = 2.25
A x ( 10 - 0.25 - 3/4 ) = 2.25
A x 9 = 2.25
A = 2.25 : 9
A = 0.25
Tìm y:
Y : 0,1 - y : 4 - y x 3/4 = 2,25
\(y:0,1-y:4-y\times\dfrac{3}{4}=2,25\)
\(y\times10-y\times\dfrac{1}{4}-y\times\dfrac{3}{4}=2,25\)
\(y\times(10-\dfrac{1}{4}-\dfrac{3}{4})=2,25\)
\(y\times9=2,25\)
\(y=2,25:9=0,25\)
Tìm x
x : 0,1 - x : 4 - x * \(\frac{3}{4}\) = 2,25
Ta có : \(x\div0,1-x\div4-x\times\frac{3}{4}=2,25\)
\(\Leftrightarrow x\times10-x\times\frac{1}{4}-x\times\frac{3}{4}\)
\(\Rightarrow x\times\left(10-\frac{1}{4}-\frac{3}{4}\right)=2,25\)
\(\Rightarrow x\times9=2,25\)
\(\Rightarrow x=2,25\div9=0,25\)
